I am running Windows 10 on a new Lenovo P71 computer. Everything was working fine, until today when I started having trouble typing into my Office 365 programs. When I type nothing happens, though after several seconds the typing starts working. I don't have this problem with other programs (such as what I'm typing now), only in the Office 365 programs. Any idea what the problem is and how I can fix it? I've tried both rebooting the Office programs and the computer, but the problem persists.
